gmentoo UNITED STATES PATENT DFFICE- CAN PUNCT'URING AND POUBINGATTACHMENT;

Specification of Letters Patent.

Patented Jan. 25, 1921.

Application filed February 25, 1919. Serial No. 279,216.

To all whom it may concern:

Be it known that we, illman iixnnnsox and EARL R. HARTMAN, citizens ofthe United States, residin at Trenton, in the county of Mercer and tateof New Jersey, have invented certain new and useful 1 111- provements inCan Puncturing and Pouring Attachments, of which the following 1s aspecification. V

This invention relates to can attachments and has for its object toprovide a pouring or dispensing device particularly adapted forapplication to cans containing .such liquids as milk whichare'usuallydispensed at spaced intervals of time, the can being utilized as astorage receptacle.

Another objectis the provision of a pouring attachment for cans providedwith two tubes having communication with the interior of the can andadapted to be alternately utilized to conduct the contents of the caninto another receptacle and to provide means for admitting air to theinterior of the can to replace the liquid dispensed therefrom, the tubesbeing provided with a novel type of valve structure preventing'theadmission of air and other matter to the interior of the can when not inuse.

A still further object is to self-construct the penetrating terminals ofthe tubes as to efi'ectively retain them in position 111 the can top andthus prevent accidental displacement of the attachment.

With these and other objects in view as will appear as the descriptionproceeds, the invention comprises the novel features of construction,combination of elements and arrangement of parts which will be morefully described in the following specification and set forth withparticularity in the claims append hereto.

In the drawings:

Figure 1 represents a fragmentary side elevation of a can, partly insection, illustrating the invention applied thereto,

Fig. 2 represents a top plan view of the can and attachment,

. Fig. 3 represents a side elevation at right angles to Fig. 1, partlyin section, and

Fig. l represents an enlarged detail sectional view in the plane of theline i-4 of Fig. 1.

Referring to the drawings in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates a supporting bar having apertured terminals receiving thetubes 6 which latter are arranged in parallel relation and are solderedor otherwise permanently secured to the terminals of the rod 5. Thelower terminals of the tubes are oppositely beveled to providepenetrating points 7 which are capable of readily puncturing the top ofa can 8 to establish communication between the interior of the latterand the tubes 6. Adjacent the upper end ot the bevel, the tubes areformed with relatively narrow transverse recesses 9 adapted to receivethe inturned portion oi the punctured part of the can top to effectivelyretain the attachment in position and sealing sleeves 10 formed onrubber or similar compressible material are fitted upon the tubes 6 andagainst the terminals of the rod 5 and are designed to engage the topoff the can about the holes produced by the penetrating terminals of thetubes to prevent the leakage of the contents of the can duringdispensation thereof. The recesses 9 define transverse shoulders whichconstitute stops for limiting the inward movement of the tubes and thusprevent undue compression of the sleeves 10.

A stud 11 is riveted or otherwise hingedly secured centrally of the rod5 and supports the substantially U-shaped spring clip 12 which latter isinverted and is provided terminally with turned back clamping members 13adapted to resiliently grip diametrically opposed portions of the cam 8to assist in maintaining the attachment in operative position thereon.

Guide plates 13 are secured to the upper open terminals of the tubes 6and are formed with alined recesses receiving the reduced terminals of aspring valve member 14 the shoulders 15 of which bear against the platesand normally retain. the spring in flexed condition. By gripping anddepressing the medial portion of the spring, the reduced outer terminalsthereof are tilted up uncovering the terminals of the tubes 6 and permitting the contents of the can to be poured therefrom. As clearly shownin Fig. 1,.the lower surface of the spring slides in contact with theupper surfaces of the caps 18 effectively closing the upper terminals ofthe tubes and preventing the admission of air to the interior of the canand the inherent resiliency of the spring closure member projects theterminals thereof across the open ends of the tubes when the spring isrelieved of pressure at its medial portion.

lVhat I claim is:

1. An attachment for tin cans including a pair of tubes provided withpenetrating points, means connecting said tubes, and a spring closuremember normally closing the terminals of the tubes.

2. A can attachment including a pair of tubes provided with penetratingpoints, means connecting said tubes, and a spring closure membernormally closing the terminals of the tubes and having flexible medialportion adapted to be compressed to uncover the tubes.

3. A can attachment including a pair of tubes, caps carried by the tubesprovided with external grooves, and a spring closure member extendingbetween the tubes, normally closing the terminals of the tubes andmovable longitudinally in the grooves to uncover the tubes.

4. A can attachment including a pair of tubes, guide plates carried bythe tubes provided with grooves, a spring closure member extendingbetween the tubes, normally closing the terminals of the tubes andmovable longitudinally in the grooves to uncover the tubes, andshoulders adjacent the/terminals of the closure member normally engagedwith the plates and maintaining the closure member in a flexed tensionedcondition.

Q5. An attachment for cans including a pair of tubes, a supporting barconnecting said tubes, and an inverted U-shaped member having its webswivelly connected with the bar and provided with inwardly and upwardlyturned terminals for engaging and clamping a can.

In testimony whereof we aifix our signatures: hereto. V
